4Anisodine hydrobromide alleviates oxidative stress caused by hypoxia/reoxygenation in human cerebral microvascular endothelial cells predominantly via inhibition of muscarinic acetylcholine receptor 4显示文摘Background:Anisodine hydrobromide(AT3),an anti-cholinergic agent,could be delivered to the brain across the blood-brain barrier and has been used clinically for the treatment of cerebral ischemia/reperfusion injury.Endothelial dysfunction can be caused by hypoxia/reoxygenation(H/R)via oxidative stress and metabolic alterations.The present study investigated whether AT3 regulates the production of nitric oxide(NO)and reactive oxygen species(ROS),and the HIF-1αpathway via regulation of muscarinic acetylcholine receptors(mAChRs)in brain microvascular endothelial cells after H/R exposure.Methods:Under H/R conditions,hCMEC/D3 cerebral microvascular endothelial cells were treated with AT3.Specific inhibitors of M2-and M4-mAChRs were used to explore the mechanism by which AT3 influences oxidative stress in endothelial cells.Then,mAChRs expression was detected by western blotting and NO production was detected by Greiss reaction.The intracellular ROS level was measured using DCFH-DA probes.The expression of hypoxia-inducible transcription factor 1α(HIF-1α)was also detected.Results:While H/R induced the expression of M2-and M4-mAChRs,AT3 suppressed the H/R-upregulated M2-and M4-mAChRs.H/R also induced the production of NO,ROS,and apoptosis.AT3 and M4-mAChR inhibitors inhibited the H/R-induced production of NO and ROS and apoptosis.HIF-1αwas induced by H/R,but was suppressed by AT3.Conclusion:Thus,the in vitro evidence shows that AT3 protects against H/R injury in cerebral microvascular endothelial cells via inhibition of HIF-1α,NO and ROS,predominantly through the downregulation of M4-mAChR.The findings offer novel understandings regarding AT3-mediated attenuation of endothelial cell apoptosis and cerebral ischemia/reperfusion injury.WENLI JIANG JUNYI SHEN XIAOQIANG DU YAN QIU JIAN ZHONG ZHI OUYANG BINGMEI M.FU YE ZENG 2023BIOCELL2023,47,10:0
5Mechano-Sensing and shear stress-shielding by endothelial primary cilia:structure,composition,and function显示文摘Primary cilium is an antenna-like and non-motile structure protruding from the apical surface of most mammalian cells including endothelial cells lining the inner side of all the blood vessels in our body.Although it has been over a century since primary cilia were discovered,the investigation about their mechano-sensing and other roles in maintaining normal functions of cardiovascular system has just started in recent years.This focused review aims to give an update about the current literature for the role of endothelial primary cilia in blood flow mechanosensing and shear stress-shielding.To do this,we first summarized the characteristic features of endothelial primary cilia in terms of structure,dimension,molecular composition,and mechanical properties(e.g.,bending rigidity),which are the dominant factors for their functions in mechano-sensing and transduction,as well as vascular protection from the blood flow-induced wall shear stress.We also described the experimental techniques and mathematical models for determining the dimension and mechanical properties of the primary cilium.Then we reviewed the molecular mechanisms underlying mechano-sensing and transduction by endothelial primary cilia and the mathematical model prediction for their roles in redistribution and reduction of wall shear stresses.Finally,we briefly discussed the common cardiovascular diseases,e.g.,atherosclerosis,hypertension,and aneurysm,due to defects and malfunction of endothelial primary cilia and suggested potential targets for therapeutic treatments.HUAN YIN LIZHEN WANG YUBO FAN BINGMEI M.FU 2021BIOCELL2021,45,5:0
6Characterization of the first prototype CMOS pixel sensor developed for the CEPC vertex detector显示文摘Purpose CMOS pixel sensor has become extremely attractive for future high-performance tracking devices.It has been proposed for the vertex detector at the Circular Electron Positron Collider,which will allow precision measurements of the properties of the Higgs boson.To meet the stringent requirements for low power consumption,it is necessary to optimize the pixel sensor diode geometry to reach a high charge-over-capacitance ratio that allows reduction in analog power consumption.Methods Collection electrode size and footprint are two critical elements in sensor diode geometry and have deciding impacts on the charge collection performance.A prototype CMOS pixel sensor,named JadePix-1,has been developed with pixel sectors implemented with different electrode sizes and footprints,and its charge collection performance has been characterized with radioactive sources.Results Charge-to-voltage conversion gains for pixel sectors under test have been calibrated with low-energy X-rays.Characterization results have been obtained for equivalent noise charge(below 10e−),charge collection efficiency(around 40%),charge-over-capacitance ratio(above 0.015 V)and signal-to-noise ratio(higher than 55).Conclusion Small collection electrode size and large footprint are preferred to achieve high charge-over-capacitance ratio that promises low analog power consumption.Ongoing studies on sensor performance before and after irradiation,combined with this work,will conclude the diode geometry optimization.L.J.Chen H.B.Zhu X.C.Ai M.Fu R.Kiuchi Y.Liu Z.A.Liu X.C.Lou Y.P.Lu Q.Ouyang X.Shi J.Tao K.Wang N.Wang C.F.Yang Y.Zhang Y.Zhou 2019Radiation Detection Technology and Methods2019,3,3:0
7Endothelial surface glycocalyx and vascular mechano-sensing and transduction显示文摘Introduction The endothelial cells(ECs)lining every blood vessel wall constantly expose to the mechanical forces generated by the blood flow.The EC responses to these hemodynamic forces play a critical role in the homeostasis of the circulatory system.In addition to forming a transport barrier between the blood and vessel wall,vascular ECs play important roles in regulating circulation functions.Besides biochemical stimuli,blood flow induced(hemodynamic)mechanical stimuli,such as shear stress,pressure and circumferential stretch,modulate EC morphology and functions by activating mechanosensors,signaling pathways,and gene and protein expressions.The EC responses to the hemodynamic forces(mechano-sensing and transduction)Wanyi Yen Jinlin Yang Min Zeng John M.Tarbell Bingmei M.Fu 2013医用生物力学2013,28,S1:0
